b) HEMP Protection.  When such protection is required, the
criteria will be found in MIL-HDBK-1012/2 and the BESEP.  Bonding. Bonds between cabinet chassis and the raised floor shall
not exceed a design goal specified resistance of 5 milliohms. Shielding
Shielding shall be provided as needed for each case.
b) Shielding for red information areas shall be as set forth in
the BESEP.
Oceanographic Facilities. Oceanographic Centers process signals
from underwater areas via submarine cables (commonly referred to as sea
cables) to a shore processing facility.  The shore equipment is normally
located in a Terminal Equipment (TE) building.  Specific guidance concerning
the layout of the facility, physical security requirements, and types of
systems will be set forth in the BESEP.  The TE building may also contain
administrative offices and electronic power generation equipment.
Architectural and Structural.  The facility shall comply with the
general requirements of Section 3.  Special requirements shall be as set forth
in the BESEP.
Mechanical.  Basic design criteria are provided in Section 4.
Special requirements shall be as set forth in the BESEP.
Electrical  Underwater Cable.  Typically, one or more buried cables run from
the sea to the TE building.  The signals on these cables are extremely
sensitive to interference from nearby AC power circuits and strong RF fields.
No electric conductors, equipment, facilities or structures of any kind shall
be installed in the vicinity of these cables. A set of guidelines for
installations in the vicinity of underwater cables is given below.  Written
permission from the SPAWAR (PMW-180) is required, on a case-by-case basis, to
grant waivers from these guidelines.  Quiet Zones. Quiet zones for a typical site are defined in
Figure 16.
a) Quiet Zone A shall be kept completely free of AC power
b) No structures or facilities of any kind shall be installed in
Quiet Zone B except as specifically noted below.  This restriction
specifically includes antennas of any kind, overhead or buried communication
lines, and AC power lines.
(1) AC-powered security lights may be installed in Quiet Zone
B provided they are designed to prevent the injection of power-line frequency
currents into the earth in the quiet zone.  Isolation transformers and ground
